Proper Oil Change Intervals

Most car owners are not sure when what is the proper time to change the oil in their car. If you were to read all the information available online on the topic, you will find distinct schools of thought; experts who believe that the oil in a vehicle should be changed every 3000 miles. On the other hand, there are some other people who believe that most engine oils today are made with fluids of different densities and have detergent in them which allow them to be effective for longer mileage periods. As a matter of fact, most automobile manufacturers also recommend that engine oil should be changed every 5000 miles or one year, whichever comes first unless you use synthetic oil.
